-Fabricated a bracket that will secure the cabin heat cable right before it goes to the acutator arm on the mixer box. -Trimmed the cable to length -Installed the grommets -Assembled and checked operation Looks like it will work fine. I need to open up the fastern holes for #8 screws or AN3 bolts (haven't decided yet) and then proseal everything on.
Viewed from the left side - note the angle bracket that supports the cable after it exits the firewall
Another angle from the right. The bend is pretty acute, but it works fine
